|---|---|---|
| lisitsyn | geektoni: hey | 09:55 |
| geektoni | Do you have some time? :) I have some question regarding Tags. | 09:55 |
| lisitsyn | yes | 09:56 |
| -!- HeikoS [~heiko@host-92-0-178-129.as43234.net] has joined #shogun | 09:56 | |

| geektoni | ok, thanks :) first of all, https://github.com/shogun-toolbox/shogun/projects/6 | 09:56 |
| geektoni | is this a list related to my project? | 09:57 |
| geektoni | or is just for you devs. Because I see things that I should also do while porting shogun to Tags. | 09:57 |
| lisitsyn | geektoni: for sure you're welcome to do anything from this project :) | 09:58 |
| geektoni | ;) because for example, as is written there, equals and close will stop working, since we will drop the Parameter class. | 10:00 |
| lisitsyn | geektoni: yeah but before dropping we have to come up with working non-owning any | 10:00 |
| -!- goksinen [~goksinen@rrcs-50-75-193-138.nyc.biz.rr.com] has joined #shogun | 10:00 | |
| lisitsyn | which can take a pointer and treat it as any | 10:00 |
| geektoni | so the final result will be have tags and also have parameters defined into the same class? | 10:02 |
| lisitsyn | no it is just tags | 10:02 |
| lisitsyn | in the end we drop TParameter thing | 10:02 |
| -!- goksinen [~goksinen@rrcs-50-75-193-138.nyc.biz.rr.com] has quit [Ping timeout: 255 seconds] | 10:05 | |
| geektoni | mmh, I got a bit lost at the "any" part. I know it is used inside tags, but what do you mean by non-owning? | 10:09 |
| lisitsyn | geektoni: in SG_ADD we wrap the pointer to member variable | 10:09 |
| lisitsyn | and we also have map<Tag, any> which stores all the parameters | 10:10 |
| lisitsyn | we want to make it able to use the same SG_ADD but to put it into this map | 10:10 |
| lisitsyn | but this means any should just take the pointer and do no memory management | 10:10 |
| lisitsyn | by default it 'owns' the memory | 10:10 |
| lisitsyn | so there is an idea to introduce different policies (you may check the any's code) | 10:11 |
| lisitsyn | but it is broken still | 10:11 |
| lisitsyn | meh :) | 10:11 |
| lisitsyn | int value = 3; | 10:11 |
| lisitsyn | auto any_value = wrap(&value); | 10:12 |
| lisitsyn | value = 4; | 10:12 |
| lisitsyn | assert any_value.get() == 4; | 10:12 |
| lisitsyn | this works | 10:12 |
| lisitsyn | but | 10:12 |
| lisitsyn | any_value = any(8); | 10:12 |
| lisitsyn | kaboom | 10:12 |
| geektoni | mmh, I understand. | 10:16 |
| geektoni | but I thought that register_member() was enough to register a parameter inside the map. | 10:17 |
| lisitsyn | using TParameter | 10:17 |
| lisitsyn | but not the modern approach TM | 10:17 |
| geektoni | ok! Got it! :) | 10:23 |
| geektoni | btw, I'm a little puzzled by the behavior of Some<> (probably because I'm not a C++ master). | 10:28 |
| geektoni | https://gist.github.com/geektoni/e78b204bb5a8fd1f17c933ab9c0912e8 | 10:28 |
| geektoni | line 27,28 | 10:28 |
| geektoni | Why does this example compile? | 10:29 |
| geektoni | ^ lisitsyn | 10:29 |
| lisitsyn | geektoni: there is operator* that is called | 10:30 |
| lisitsyn | I'd suggest adding a print to check if it is called | 10:31 |
| lisitsyn | and then dynamic cast is happening | 10:31 |
| geektoni | oh I see. Thanks :D it's clearer now! | 10:34 |

| lisitsyn | mikeling: sup | 11:23 |
| mikeling | lisitsyn: hey, I write some code in Linalg like this https://pastebin.mozilla.org/9022153, but it keeps telling me ‘matrix_prod’ was not declared in this scope, | 11:24 |
| mikeling | https://pastebin.mozilla.org/9022154 | 11:24 |
| lisitsyn | what's matrix_prod? | 11:25 |
| mikeling | http://shogun.ml/api/latest/namespaceshogun_1_1linalg.html#a7debb2540ef822fd0cd9ac74bf0ea798 here | 11:25 |
| lisitsyn | ah | 11:25 |
| lisitsyn | I guess you miss some include then | 11:25 |
| mikeling | but I write it in the LinalgNamespace.h | 11:26 |
| mikeling | so I don't think I need to include linalg:: or other file due to the I define it just in the same place with 'matrix_prod' | 11:27 |
| lisitsyn | mikeling: check args and namespaces | 11:30 |
| lisitsyn | just in case | 11:30 |
| mikeling | lisitsyn: here is the gist https://gist.github.com/MikeLing/23158041b7fffdcbe749ff531db317cd#file-patch-cc-L130 I just created | 11:33 |
| mikeling | a is a SGMatrix, x is a SGVector. I can't found anything from the args | 11:35 |
| lisitsyn | uhm | 11:36 |
| lisitsyn | can't see either | 11:39 |
| mikeling | Could you find find anything in the log https://pastebin.mozilla.org/9022154? | 11:41 |

| @wiking | hello morning | 12:57 |
| @wiking | :) | 12:57 |
| @wiking | mikeling, still stuck? | 12:58 |
| @wiking | have you tried shogun::linalg::matrix_matrix_prod | 12:59 |
| @wiking | ? | 12:59 |
| @wiking | hahah | 13:01 |
| @wiking | this is very sad | 13:01 |
| @wiking | http://scikit-learn.org/ml-benchmarks/ | 13:01 |
| @wiking | :) | 13:01 |
| @wiking | although: "Last Update: July-2011" | 13:02 |
| mikeling | wiking: hey | 13:13 |
| @wiking | ho | 13:13 |
| mikeling | No I haven't | 13:13 |
| @wiking | try that | 13:13 |
| mikeling | But why matrix_matrix_prod? | 13:13 |
| @wiking | oh no | 13:18 |
| @wiking | that is just a typo | 13:18 |
| @wiking | shogun::linalg::matrix_prod | 13:18 |

| @wiking | no problem | 14:25 |
| mikeling | still doesn't work https://pastebin.mozilla.org/9022161 | 14:26 |
| mikeling | and I don;t think we need linalg:: | 14:26 |
| @wiking | should | 14:27 |
| mikeling | due to cblas_dgemv just in the linalg namespace | 14:27 |
| mikeling | https://gist.github.com/MikeLing/23158041b7fffdcbe749ff531db317cd#file-patch-cc-L87 | 14:27 |
| @wiking | if you check | 14:27 |
| @wiking | the header starts like this | 14:27 |
| @wiking | namespace shogun | 14:27 |
| @wiking | { | 14:27 |
| @wiking | namespace linalg | 14:27 |
| @wiking | { | 14:27 |
| @wiking | src/shogun/mathematics/linalg/LinalgNamespace.h | 14:27 |
| @wiking | mikeling, but i wouldn't add to linalg | 14:29 |
| @wiking | such a method as +void cblas_dger(T alpha, const SGVector<T> x, const SGVector<T> y, SGMatrix<T>& A) | 14:30 |
| @wiking | az it's name is crazy | 14:30 |
| @wiking | so i would just simply do an ifdef | 14:30 |
| @wiking | in Gaussian.cpp:169 | 14:30 |
| @wiking | for HAVE_LAPACK | 14:30 |
| @wiking | and put there the implementation | 14:30 |
| @wiking | if lapack is not available | 14:30 |
| -!- goksinen [~goksinen@rrcs-50-75-193-138.nyc.biz.rr.com] has joined #shogun | 14:31 | |
| mikeling | hmmm but we call cblas_dgemv multiple times | 14:32 |
| mikeling | which means we need write same things again and again | 14:33 |

| @wiking | mmm | 14:37 |
| @wiking | you can call it a function | 14:37 |
| @wiking | but please dont call it | 14:37 |
| @wiking | cblas_dgemv | 14:37 |
| @wiking | az that is almost like a random set of strings | 14:37 |

| @wiking | mikeling, in my linalgnamespace | 14:42 |
| @wiking | the first declaration of matrix_prod | 14:42 |
| @wiking | is line 516 | 14:42 |
| @wiking | is it the same for you? | 14:42 |
| @wiking | because then dont wonder | 14:42 |
| @wiking | that /home/mikeling/shogun/src/shogun/mathematics/linalg/LinalgNamespace.h:387:21: error: ‘matrix_prod’ is not a member of ‘shogun::linalg’ | 14:43 |
